[ame=http://en.wikipedia.org/wiki/Drug_policy_of_the_Netherlands]Wikipedia[/ame]Netherlands has a high anti-drug related public expenditure, the second highest drug related public expenditure per capita of all countries in EU (after Sweden). 75% is law enforcement expenditures including police, army, law courts, prisons, customs and finance guards. 25% is health and social care expenditures including treatment, harm reduction, health research and educational including prevention and social affairs interventions.
I suppose we might also consider that the Dutch have a less violent society. I don't know whether that's due to their drug policy, their handgun policy, the level of poverty, or some other social or demographic factors.
